具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例，根据直播控制中心下发的指令创建实时转码任务并分配任务标识，将实时转码任务的日志数据重定向至预设目录，在实时转码任务开始执行后，通过解析预设目录中的日志数据来监控实时转码任务的运行状态是否出现异常，实现了对实时转码系统的有效监控，提升了实时转码系统的稳定性，为直播业务提供了有效保障，有助于为网络用户提供更稳定的视频直播服务。
图1是本申请实施例提供的一种实时转码的监控方法，适用于实时转码系统，该方法包括以下步骤S10-S12。
在步骤S10中，接收直播控制中心下发的实时转码任务创建指令。
实时转码系统与直播控制中心之间定义了实现创建实时转码任务、查看实时转码任务状态、终止实时转码任务、重启任务执行模块和任务监控模块等功能的网页(Web)接口，供编辑人员根据直播业务的变化来启动和停止对应的实时转码任务。
当接收到直播控制中心下发的指令后，执行上述对应操作。如果指令数据不符合预定义的数据格式，例如，缺少直播流标识(ID)、或者缺少输入流和输出流对应的地址等，则返回错误消息通知直播控制中心，不执行对应的操作。
在步骤S11中，创建并执行对应的实时转码任务，为实时转码任务分配对应的任务标识，将实时转码任务的日志数据重定向到预设目录。
每接收到一个实时转码任务，启动一个实时转码任务线程实例并分配对应任务标识，做为该实时转码任务的全局唯一标识。
考虑到单台实时转码设备的转码容量问题以及中控单元对各台实时转码设备负载的限制，不会出现大量实时转码任务同时在单台转码机运行的状况，因此能够在实时转码设备的内存中创建一个全局任务管理字典，并将任务标识作为键(key)存入全局任务管理字典中。
解析实时转码任务数据，以获得该实时转码任务的属性参数。包括检测输入流的传输协议，例如实时消息传输协议(Real Time Messaging Protocol，RTMP)、超文本传输协议(HyperText Transfer Protocol，HTTP)和微软媒体服务器协议(Microsoft Media Server Protocol，MMS)等；配置输出流的用户代理信息(user_agent)、HTTP头(headers)信息等；根据转码档次确定不同的码率之后，在该实时转码任务线程实例下启动转码子进程，开始执行实时转码任务，将该转码子进程的进程号记录到全局任务管理字典内相应的任务标识下，并将转码子进程的日志数据重定向到预设目录，该预设目录是任务监控模块能够访问的目录，以利于任务监控模块获取日志数据并执行监控操作。
在转码子进程的运行过程中，如果接收到直播控制中心的停止(Stop)信号，则转码子进程退出，停止转码任务；如果未接收到停止信号，遇到子进程退出的情况，则重启一个转码子进程并更新全局任务管理字典中的进程号。
在步骤S12中，根据任务标识解析预设目录中的日志数据，监控实时转码任务的运行状态。
通过任务标识来区分不同的实时转码任务，从对应的日志数据中获取其转码子进程当前的进度信息(通常出现在日志数据的最后3行)，进度信息包括时间信息、码率(比特率)、图像尺寸和负载信息。
其中，时间信息是转码子进程当前已转码的直播视频流的总时长；码率是已转码的直播视频流的码率，图像尺寸是转码后的直播视频流图像的宽和高；负载信息是该 实时转码任务当前所占用的系统资源。
可以周期性的解析日志数据并通过上述信息来监控每个实时转码任务，也可以在预设的固定时间点解析日志数据并通过上述信息来监控每个实时转码任务，以检测实时转码任务是否运转正常，识别出已卡死(stuck)或者占用系统资源过大的实时转码任务。
本实施例中，将每个实时转码任务的日志数据重定向到预设目录，对预设目录中的日志数据进行解析，实现对实时转码任务运行状态的监控，提升了实时转码系统的稳定性，为直播业务提供了有效保障。下面对监控实时转码任务的运行状态的方式分别进行说明。
在一个实施例中，如图2所示，步骤S12可进一步实施为以下步骤S121-S124。
在步骤S121中，从日志数据中获取实时转码任务的进度信息。
在步骤S122中，周期性的获取进度信息中的时间信息来判断时间信息的更新状态。
获取时间信息后，将其更新到时间字典内，时间字典也是以实时转码任务的任务标识为键(key)，对应保存实时转码任务的时间信息。
每隔预设时长(例如10秒)获取一次时间信息，当获取到的时间信息与上一次获取的相比没有更新时，代表该实时转码任务可能出现了卡死。
在步骤S123中，当时间信息持续未被更新的次数大于或等于第一预设门限时，确定实时转码任务处于异常状态。
时间信息持续未被更新的次数大于或等于第一预设门限，代表该实时转码任务已卡死的时间过长，那么，可确定该实时转码任务出现了异常。例如，每隔10秒获取一次时间信息，时间字典中某个任务标识的时间信息没有更新的次数超过了3次，那么该实时转码任务已卡死的时长很可能已经超过了30秒，那么确定该任务标识对应的实时转码任务出现了异常。
在步骤S124中，根据任务标识重启实时转码任务。
在全局任务管理字典中，查询到该任务标识下的转码子进程的进程号，根据进程号重启该实时转码任务的转码子进程。为重新启动的转码子进程重新分配新的进程号并保存在全局任务管理字典相应的任务标识下。
本实施例中，通过进度信息中的时间信息是否持续更新来判断实时转码任务是否出现已卡死的现象，识别出卡死现象后重新启动转码子进程，从而尽快修复对于直播业务的实时转码处理，保证直播业务的正常播出。
在一个实施例中，如图3所示，步骤S12可进一步实施为以下步骤S125-S124。
在步骤S125中，周期性的获取日志数据中的更新日志。
每隔预设时长(例如10秒)获取实时转码任务日志数据中更新日志，以判断该实时转码任务是否仍在继续运行。如果没有获取到更新日志，代表该实时转码任务可能已停止运行。
在步骤S126中，当未获取到更新日志的时长大于或等于第二预设门限时，确定实时转码任务处于异常状态。
当获取不到更新日志的时长大于或等于第二预设门限时，代表该实时转码任务没有继续运行的持续时间过长，那么，可确定该实时转码任务出现了异常。
在步骤S127中，根据任务标识重启实时转码任务。
本实施例中，通过是否能够获取到更新日志来判断实时转码任务是否在继续运行，识别出该实时转码任务无法继续运行的持续时间过长时，重新启动转码子进程，从而尽快修复对于直播业务的实时转码处理，保证直播业务的正常播出。
在一个实施例中，如图4所示，步骤S12可进一步实施为以下步骤S128-S1211。
在步骤S128中，从日志数据中获取实时转码任务的进度信息。
在步骤S129中，周期性的检测所述进度信息中的负载信息。
负载信息可以是实时转码任务对系统内存的占用率，或者是对CPU的使用率等。
在步骤S1210中，当负载信息大于或等于第三预设门限时，确定实时转码任务处 于异常状态。
负载信息大于或等于第三预设门限时，代表该实时转码任务当前的负载过大，可能是运行时间过长或者是视频数据处理量过多造成的。例如，当实时转码程序占用了大于40％的系统内存时，判定该实时转码任务异常。
在步骤S1211中，根据任务标识重启实时转码任务。
本实施例中，通过进度信息中的负载信息来判断实时转码任务的负载是否过高，当该实时转码任务负载过高时，重新启动转码子进程，从而释放其占用的系统资源，使重新启动的转码子进程能够获取更佳的处理效率。
而在另一个实施例中，可以通过图2、图3和图4所提供的监控方式同时并行对实时转码任务进行监控，当实时转码任务出现已卡死、出现没有继续运行、当前负载过高等任意一种情形时，都会对实时转码任务的转码子进程进行重启，从而从多个维度对实时转码任务进行监控，进一步有助于为网络用户提供更稳定的视频直播服务。
在一个实施例中，如图5所示，该实时转码的监控方法进一步包括以下步骤S13-S14。
在步骤S13中，在实时转码系统重启之后，从直播控制中心获取当前所有的实时转码任务。
需要对实时转码系统进行重启时，由于实时转码任务均由内存中的全局任务管理字典来维护，因此在重启后当前的全局任务管理字典将无法保存。
实时转码系统在重启后从直播控制中心根据当前仍在直播中的业务获取实时转码任务。
在步骤S14中，创建并执行获取到的实时转码任务并重新分配对应的任务标识。
创建实时转码任务并重新分配任务标识，在内存中重新创建一个全局任务管理字典，以重新分配的任务标识为键(key)。后续转码处理与实时监控的过程仍然与重启之前相同。
该实时转码系统在重启之后也能够很快重新创建实时转码任务，使仍在继续的直 播业务能够迅速恢复正常。
在一个实施例中，该实时转码的监控方法中的步骤S11可进一步实施为以下步骤S111-步骤S113。
在步骤S111中，创建对应的实时转码任务，为实时转码任务分配对应的任务标识，将实时转码任务的日志数据重定向到预设目录。
在步骤S112中，解析实时转码任务，获取其中的自定义转码属性信息。
自定义转码属性信息可以是由直播控制中心的编辑人员设置的转码属性信息，包括码率范围信息、音轨信息、声道信息、字幕信息、音频滤镜以及视频滤镜中的一个或多个，可以为直播视频添加更丰富的内容供用户选择或者提高直播视频的观看效果。
在步骤S113中，根据自定义转码属性信息执行实时转码任务。
本实施例中，在转码任务执行之前解析出实时转码任务中的自定义转码属性信息，根据自定义转码属性信息执行转码内容，提高了直播视频的观看效果，为直播视频添加更丰富的内容供用户选择。
